Final answer:
Among President Wilson's 14 points was the proposal to form a League of Nations, intended to mediate disputes and prevent wars.
Step-by-step explanation:
Among President Wilson's 14 points, the proposal was to form a league of nations. This concept was based on the idea of establishing a new international organization that would mediate disputes between nations and prevent aggressor nations from attacking others. The League of Nations aimed to create a 'concert of nations' to promote peace and mutual protection, embodying the spirit of collective security where an attack on one member would be considered an attack on all.
